WALL sen.

To all whom it may concern:

Be it known that I, MATTHEW F. Bsrnn, a citizen of-the United States,residing in the city of Kenosha, county of .Kenosha, and

State of Wisconsin, have invented certain new and useful Improvements in"Wall Beds, of which the following is a specification.

. My invention relates to improvements in Wall beds and has particularreference to that type of wall bed which, when folded into verticalposition, is capable of being concealed in a suitable recess.

The principal objects of the invention are to rovide a Wall bed of theclass described. wh1ch,.when unfolded or adjusted in horizontal oreffective position has the appearance of an ordinary bedstead and islocated with reference to the wall of the room in a location permittingfree access of thenceessary air for proper ventilation; to pro vide awall bed of the class described which may be quickly and convenientlyshifted or adjusted into either of its two positions; to provide a wallbedof the class described having improved means for securing the bedding.to the bedstead so that themattress, pillow, or other bedding will notbecome displaced when the bed is adjusted in vertical or foldedposition; to provide improved means fol-automatically causing thevarious parts to assume their proper positions; to provide improvedmeans for locking the op erative parts of the bed in the desiredadjusted position; to provide a device embodying a comparatively fewmechanical partsand those" parts being of simple and ruggedconstruction; to provide a construe tion of the class described whichshall he comparatively inex iiensive to manufacture andpracticallyfool-proof and in general, to provide an improved efiicientwall bed of the character referred to.. p

able recess in the wall of the room, the opening into the recess beingclosed by a door, or a pair of. doors when the bedstead is in therecess. The rear of said recess is equipped with a pair of suitablespaced apartuprights 20 and 21 to which the so 0- porting frame 22 forthe bedstead is connected by means of a suitable parallel inotlon whichwill permit horizontal movement oi the supporting frame 22 out of the recessnhen maintaining the said frame 22 in vertical position. Such meanscomprises a set of tour pairs of links 23 and 24.- said links being; ofequal length and pivoted together. at their adjacent ends as shown at25. The opposite ends of the. said links 23 and :24 are pivotedrcspectivelv to small brackets 25 secured the uprigrhts 20 and 21.. andto points of the vertical supporting frame ".llhelinks 23 and 2st onopposite sides (Hi the supg'iorting frame 22 are caused to move inunison by horizontal rods 26 rig};- idly uniting the rear ends of thelengths 23 ad acent or at their pivotal connections with the b1": clrets25 and the upper links and the lower links are caused to move in unisonbv a pair of vertically extending rods or links the ends of which arepivotallv connected to the pivots between the links 23 and 24. Each sideor". the vertical frame 22 is equipped with a pair of supporting wheelsor rollers 28 which enable the bedstead and i frame to be moved in orout of the recess witi'iout injury to the rug or floor or" the roomitwill be understood that the lengths of the links 23 and 24 are such thatthe vertifrom the back of the recess a substantial.

' distance thereby to secure free access of-air to the head of thebedstead, th? head of the bedstead comprising in part the upper portionof the frame 22. It will be, noted that in order to conform to presentday standards of bedstead designs, the upper port on of said verticalframe 22 is constructed with suitable pillar rods 29 matching the fillerrods 30 of the footcnd 31 to the bedstead.

The bed bottom 32 may be of any approved construction,although in thepresent instance I have shown a spring mattress composed of a series ofhorizontal strap members 33 connected transversely by in dividual helicals 34, the slats at their ends being connected by means oflongitudinal D in Figs.

helicals 35 to a pair of opposed transverse angle iron members 36 and37. The said angle iron members 36 and 37 are connected together andspaced apart by means of apair of side tubes 38 and 39 which areequipped with suitable risers 40 and 41. prefer to equip the head end ofthe bedstead with a low sub-head 42 for the purpose of supporting thematress 43 when the bedstead is swung up into vertical or foldedposition. Said sub-head 42 is secured to the vertical flange of thecross angle 36 by an desired. means such as bolts or rivets.

t will be noted that the foot end 31 of the bedstead is rigidly securedto the risers 4:1 by means of joint connections 43 which needs-not bedescribed in detail. The said foot end 31, which in the presentinstance, is constructed of rectangular tubing, is jointed substantiallymidway of its vertical height as shown at 44: so that .the bottomportion 45 of the said foot end may be folded down to lie parallel withthe bed bottom or mattress frame as shown in Fig. 2. It will also beobserved that in order to conserve space the side tubes 38 of themattress frame are offset at their foot endsas shown at 46 so that thefoldable portion 455 of the foot end of the bedstead will not projectoutwardly beyond the said tubes 38 when thebed is in folded position.

The details of the pivotal connection between the upper portion of thefoot end 31 and the lower portion 45 thereof are shown 3 and 4, uponexamination of which it wi be seen that the hollow post 47 of the upperportion of the bed end 31 is equipped with a cast iron filler 48vertically slotted as shown at 4%) in order to admit a tongue or lug 50on a corresponding castiron filler member 51 sdcured in the upper end ofthe post of the foldable portion 45 of the foot' end. A transverse pin52 rigidly secured across the slot 49 servcs to pivotally connect the.filler 48 and 51, the lug 50 being suitsuilicient bodily longitudinalmovement'ofthe bottom section of the foot end to cause the edges of theleg parts to come together when the bedstead is in horizontal position.When the bedstead is in effective position the leg portion +25 of thefoot end is locked in vertical position by means of a small link 54 oneend of which is pivoted to one of the legs as shown at 55, the other-endbeing 1 slotted to engage a headed cured in the tube 38.

The supporting frame 22 at each side thereof has a rectangular loweroutwardly projecting portion 56, the lower outer corn ers of saidextension 56 being connected by means of a length of angle iron 57. Theupper outer corners 5S constitute supports in which the matress frame ispivotally mounted on a. horizontal axis. Such pivotal mounting comprisesa pair. of pins 59 fixedly secured in'the frame corners 58 andprojecting inwardly to loosely. fit corresponding apertures formed inthe side tubes 38 andv 39 of the mattress frame. The said mattress tubes38 and 39 are united together pin fixedly seadjacent to the pivotal axisby means of a c pair of transversely extending-angle irons (i0 and 61placed back to together through their adjacent flanges. The angle iron61 and the angle iron 57 are perforated at intervals to accommodate thehooked ends of a series of coil tension springs .62, the purpose ofwhich is to assist in the raising of the outer end of the bedstead when'it is desired to swing the same upwardlyfinto folded position. In Figs.1, 8 and 9 I have shown a device -for automatically locking the bed inhor-i= back and riveted zontal'or extended position so as to prevent it'from folding accidentally when the. weight is unevenly distributed; Suchdevice comprises a small locking dog 63,"the' lower end of which isloosely pivoted on a pin 64 fixed in a one side of the subhead 4C2heretofore referred to. i

The pivotal movement of said locking dog 63 is limited by a' pin 66 alsosecurely fixed in thesaid flange. 65. said pin 66 fitting loosely withina suitable slot 67 punched in the locking dog 8 and 9. The upper end ofsaid'locking dog is formed with an inclined limb 68., the function ofwhich is to engage a pin (it) fixed in the frame 22 when the bed isbeing uninner or lower end of the inclined portion (38.moves past andabove the-fixed pin .69

whereupon the said dog 133. will drop back and 'assume the positionshown in Fig. 9

63, as shown best in F flange (55 projecting from therebypositivelylocking the bed against a reverse pivotal 'movement.

In. this connection it may be stated that n. practice I find itpreferable to give the pin iii-3 a slight amount of play beneath thelatch portion when the latter is engaged with said pin By reasonof suchslight slack-- ness i am able to unlock the said latch or dog 6? withoutactually manipulating the same manually. This is done in the followingmanner:

I first lift up the foot end of the bedstead. an inch or so, the playbetween the locking pin 69 and the latch part 70 permitting suchmovement. I then drop the foot end of the bed, whereupon the jarringaction in conjunction with the, inertia of the dog 63 will cause thesame to jump or swing outwardly suflicient distance to disengage the pin69 from the latch part 70. Then by again 11i. rly raisin the foot end ofthebed sev' eral inches beiore the latch has a chance to drop back againinto locked position the dog is prevented from. relatching. I am thenable to fold up the bedstead without the necessit of manually holdingthe dog in unlocked positionf Improved means are employed for securingthe bedding in position when the bedstead is in fol relation. Tothis-end I mounttowards the foot end of the tubes 38 and 39 or". themattress a pair of cast brackets 21 and Fl said brackets havingapertured lugs 72 and 73 constituting pivotal bearings for the inwardlybent ends fi l and 7-3 of a tubular bail member 76 iitending across thefoot of bedstead. To the inner end of the bail part I rigidly secure aratchet plate 77, the teeth 78 of which are substantially arrangedconcentrically with the pivotal axis of the bail member. Said ratchetteeth 78- are arranged to-co-operate with a ratchet dog 79 rigidlysecured to a small. shaft 80 pivotally mounted in the bracket 72 andhaving its-outer and bent at right angles so as to provide a suitablehandle 81.

" It will be apparent that when the bail '(6 is adjusted in the positionshown in Fig. 2 of the drawings so as to engage the pillow and otherbedding, the ratchet and dog will be in the position shown in Fig. 7 andit will be seen that a reverse or upward movement of the bail 76 will beeffectually prevented. After the bedstead has been unfolded it is asimple matter to unlock the ratchet dog 79 by means of the handle 81whereupon the bail can be swung outwardly into the. position shown inFigs. 1, 5 and 6 thus releasing the beddin It will boobserved that whenthe bail is in such last named position it is so located as to lie inthe space between the upper edge of the foot end 'of the mattress andthe foot end of the bedstead and does not interfere with the comfort ofthe occupant.

In the preferred construction I employ special means "for automaticallymoving the bedstead supporting'l'rame in or out or its sustaining recesswhen. tl e bedstead 1S l OltlG d or unfolded asthe case may be. To thisend, and referring particularly to Figs. 11, l2, l3 and 14, it will benoted that to the bottom of the subhead 452, and at one side thereof,.l'. pivotally connect, by means of a pin 82, the outer end of aboomerang shaped link 83, the inner end of said link being slotted asshown. at Site slidably engage the headed pin fixed in 2. lugprojectingmpwardly from one of the links 24-. Tliediinensions of thevarious parts are such. that the operation is as follows:

Fig. 11 shows the bed in a position similar 7 seen that the pin 85 is atthe extreme end of 1 the slot. In closing the bed the outer end thereofis, of course, elevated which causes the pin 82 to swing around the mainpivotal axis Such downward swinging movement of the pin 82 causesrelative movement of the pin 85 along the slot Set, said slot 84 madelong enough to permit the pins 85 82 and 59 to be located in a straightline (as shown in dotted lines in. Fig. .11), before the opposite end ofthe slot 84. engages said pin 85. A further upward swinging movement ofthe bedstead on its main pivotal axis caiises the pin 85 to recederelatively to the slot 84: until the parts occupy the position shown inFig. 12. where it will be seen that the pin 85 is subs antially half wayalong the length the slot 84 While the outer angle or bend has engagedthe upper edge of the angle iron 3?. F

Upon further upward swinging movement of the bedstearhand consequentdepression of the pin 82, the link 83 will operate as a lever upon theupper edge of said angle iron 87, thus causing the pin 85 to moveupwardly, Thus by the time that the bedstead approaches its verticalfolded position, the :pin 85 will have been moved upward to such anextent as to cause a considerable collapsing movement of the links 23and 24, thus drawing the main bedstead Supporting frame toward and intothe recess. a

After the pin 85 has-risen a certain. dis, tance, due to the said leveraction of the link 83, the bend 86 of said link moves beyond the upperedge of the angle iron 8'? and into such position that the pin 85engages the outer end of the slot 84. During the final upward swingingmovement of the bedstead. the said link 83 functions purely.

as a link, bearing outwardly upon the pin 85 and causing a.'f1irthercollapsing move ment of the said links 23 and 24c. in this connection itshould be observed that when the bed is being folded considerable forceis applied to ,the .foot end of the bedstead,

which force; is obviously a pliedfin a direc tion tending to cause thebedstead to move into the recess thereby materially assist ing the link83 in moving the frame into the recess.

- to cause the lower end-of the slot ",l.imited thereby 3 5' In additionto its function, Whemthe bedstead is being folded the link Stitandassociated parts are effective to extend t e links .23 and 24 and movethe bedstead oiit of the recess wheat-he bed is extended or unfolded inthe position as shown in Fig. 1. By reference to Figpl l it will beobservedthat during the unfolding or downwardly swinging movement of thebedstead frame, the initial portion of the movement is effective 84 toengage the pin 85 whereupon the subsequent unfolding movement whichresults in an upward movement of'the pin 82 exerts a toggling actionbetween the pins 85, 82 and 59, such toggling efi'ect causes the pin 85to move away from the pin 59 and since said pin is a part of the link24;, the latter is forced to swing about its lower pivotal axis therebycausing a relative opening movement of the links 23 and 24 and aconsequent outward movement of the bedstead supporting frame from withinthe recess.

Since the precise embodiment shown herein is merely illustrative of asingle application of my invention, it should be under- ,stood that thescope of the invention is not but should be determined by reference tothe appended claims.

I claim:
